Battle of Mason's Clearing

The Battle of Mason's Clearing was a battle of the Colorado War that occurred on 12 December 1864 when the US Army attacked the Sioux village at Mason's Clearing in what is now Larimer County, Colorado. The US troops attacked the Sioux village in order to make way for the railroad's expansion, and the Sioux were massacred by the Americans and their Comanche allies; there were no Sioux warriors defending the harmless village. The "battle" allowed the Americans to expand their settlements, but it showed the cruelty of the whites against the Native Americans and the treason of some Native American tribes against other ones.
